SHUTTLE-BIND ER FoR Lojoivis.

SPECIFICATION forming part of Letters Patent No. 270,228, dated January 9, 1883.

` Application filed February 17, 1882. (No model.) i

To all whom it may concern:

Be it known that I, WILLIAM Ko'rHE, of Rockville, in the county ot' Tolland and State ot" Connecticut, have invented a certain new and useful Improvement in Shuttle-Binders for Looms, of which the following' is a description, reference being Vhad to the accompanying drawings, where- Figure lisa top view of a shuttle, an old form ot' binder, and part ofa shuttlebox of a loom. Fig. 2 is a top view ofthe sameparts, but showing my improved binder. Fig. 3 is a face View of my binder. Fig. et is a view in longitudinal horizontal section of said improved bind'er on line ww of' Fig. 3.

My invention relates to the kind of shuttlebinder that is'pivoted to the shuttle-box and is actuated by the pressure of a leaf-spring t'ast to the box and pressing horizontally upon the binder about midway of its length.

It consists in making the binder with a spring-hinge at onepoint ot its length, so that the outer end ot' the binder yields to a certain degree to the impact ol' the protection-ringer without material changein the general form and ofce of the binder` In the accompanying drawings, the letter a denotes a shuttle-box 'ot' ordinary construction; a', a shuttle; b, a binder (of metal, as

iron) as a whole; c, a binder-spring, ot steel.

My improved form ot' binder, b, as shown in Figs. 2, 4, is made up of binder part b', with the usual vertical perforations at one end for pivotal connection to the shuttle-box, and at the other end a projection, d, forming a socket tor a bolt, j', and spring g, and of binder part b, which has a similar projection, e, with a transverse teuon, e',titting in a corresponding mortise, d', in the projection d of part b. The boltj' passes through projections d and e and through the spiral spring' g and terminates at one end in a. head,f', taking against projection e, and at the otherend is provided with a nut,

t', and washer h, which is shaped to tit the cross-section of the socket in projection d, and slides readily in it. The spring g is seated in the socket in projection al, with one end pressing against the end wallot' said socket and the other end against the washer hin such manner that when the binder is bent bypress- .l ure upon its outer end and toward the shuttle the recoil of the spring restores the binder to its usual form "as soon as the pressure is removed. When the shuttle passes into the Abox back ot' this binder it does not bend outward at the joint described, but moves as a whole against the pressure of the binderspring like the old binder, the connection between the binder parts being so constructed, as shown, as to permit bending toward the shuttle only under pressure upon the outer end.

impact of the protection-finger when theshuttle is caught partly within the box, and sometimes the blow smashes a shuttle and many of the warp-threads. After such bending the binderhas to be straightened, only to be'bent short, many breaking at about the point s, Fig. 1, after a few days wear. My improved binder overcomes and obviates these defects, as it acts as a buier to the blows ot' the protection-tinger, and at the Sametime forms a more perfect binder than the old one, the outer recoil ot' the shuttle from the box.

Another advantage of my improvement is that the material (malleable iron) of the old form is replaced by cast-iron in my new device, as there is no need ot' any elasticity in the metal itself, and a saving ot' over two hundred per cent. in cost is eected..

2. In combination, binder part b', provided with projection d, having mortise d', binder j WILLIAM KOTHE.
